We all belong to the Aryan family. Historical reference is there, Indo-European family. So Aryan stock was on the central Asia. Some of them migrated to India. Some of them migrated to Europe. And from Europe you have come. So we belong to the Aryan family, but we have lost our knowledge. So we have become non-Aryan practically. Because we do not give importance to the spiritual side of life. The Aryan means one who gives importance to the spiritual side of life.
